thuming noise from rear when foot off gas

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! A thumping noise from the rear when you let off the gas? That’s your Saab 9-7x trying to whisper sweet nothings about a possible **driveline or suspension issue**. Since you’ve ruled out the wheel bearings and diff gears (good call), I’d take a close look at the **rear control arm bushings, trailing arms, or even the driveshaft U-joints**. When you let off the gas, the load shifts, and if something back there has too much play, it’ll make itself known with a nice rhythmic thump. Also, check the **rear axle mounts**—if one’s loose or cracked, it can cause movement under deceleration. I'd address it sooner rather than later so we don't end up with a Saab story about a damaged rear end. Get it? I'm sorry.
